* improved fitEllipse and fitEllipseDirect accuracy in singular or close-to-singular cases (see issue #9923)

* scale points using double precision

* added normalization to fitEllipseAMS as well; fixed Java test case by raising the tolerance (it's unclear what is the correct result in this case).

* improved point perturbation a bit. make the code a little bit more clear

* trying to fix Java fitEllipseTest by slightly raising the tolerance threshold

* synchronized C++ version of Java's fitEllipse test

* removed trailing whitespaces

jumostedu 5b095dfcb6 Merge pull request #15214 from jumostedu:matchtemplmask
* imgproc: templmatch: Add support for mask for all methods

Add support for masked template matching. Fix/scrub old implementation
for masked matching, as it did partly not even really do a meaningful
masking, and only supported limited template matching methods.

Add documentation including formulas for masked matching.

* imgproc: test: Add tests for masked template matching

Test accuracy by comparing to naive implementation for one point.
Test compatibility/correctness by comparing results without mask and
with all ones mask.
All tests are done for all methods, all supported depths, and for 1 and
3 channels.

* imgproc: test: templmatch: Add test for crossCorr

Add a test for the crossCorr function in templmatch.cpp. crossCorr() had
to be added to exported functions to be testable.

This test can maybe help to identify the problem with template matching
on MacOSX.

* fix: Fixed wrong evaluations of the MatExpr on Clang

* fix: removed crossCorr from public interface.

If it should be exported, it should be done as separate PR.
